Abstract
A silver halide photographic material is disclosed, comprising a support having thereon at least one light-sensitive silver halide emulsion layer, wherein said silver halide photographic material contains a compound by formula (IA), or which contains at least one hydroxamic acid compound having a bicyclo ring as a partial structure and represented by formula (IB).
Claims10
A silver halide photographic material comprising a support having thereon at least one light-sensitive silver halide emulsion layer, wherein said silver halide photographic material contains a compound represented by formula (IA):
- ##STR109## wherein R.sup.1a represents a hydrogen atom, a substituted or unsubstituted alkyl group having from 1 to 20 carbon atoms, a substituted or unsubstituted alkenyl group having from 2 to 20 carbon atoms or a substituted or unsubstituted aryl group having from 6 to 20 carbon atoms;
- R.sup.2a represents an alkenyl group having a total carbon number of 4 or more or a cycloalkenyl group having a total carbon atom number of 6 or more;
- provided that when R.sup.2a is a styryl group, R.sup.1a is a substituted or unsubstituted alkyl group having from 1 to 20 carbon atoms, a substituted or unsubstituted alkenyl group having from 2 to 20 carbon atoms or a substituted or unsubstituted aryl group having from 6 to 20 carbon atoms;
- and
- when R.sup.2a is an alkenyl group having a total carbon number of 17 or more, R.sup.1a is a hydrogen atom, a substituted or unsubstituted alkyl group having 7 or more carbon atoms, a substituted or unsubstituted alkenyl group having 7 or more carbon atoms or a substituted or unsubstituted aryl group having from 6 to 20 carbon atoms.
A silver halide photographic material comprising a support having thereon at least one silver halide emulsion layer, which contains at least one hydroxamic acid compound having a bicyclo ring as a partial structure, wherein said hydroxamic acid compound is represented by the following formula (IB):
- ##STR112## wherein R.sup.1b represents a hydrogen atom, a substituted or unsubstituted alkyl group having from 1 to 30 carbon atoms, a substituted or unsubstituted cycloalkyl group having from 5 to 30 carbon atoms, a substituted or unsubstituted alkenyl group having from 3 to 30 carbon atoms or a substituted or unsubstituted cycloalkenyl group having from 5 to 30 carbon atoms, and R.sup.2b represents a substituted or unsubstituted bicycloalkyl group having from 5 to 40 carbon atoms or a substituted or unsubstituted bicycloalkenyl group having from 5 to 40 carbon atoms.
